目的比较CR系统与屏-片系统在小乳房钼靶摄影中的优缺点。方法使用意大利Giotto高频钼靶乳腺机、屏-片系统和日本FUJIFILMXG5000型CR系统对233例小乳房检查者进行钼靶摄影,并对两者的应用进行研究分析。结果使用CR系统产生的图像质量明显优于屏-片系统,重拍率显著下降,被检者接受的辐射大幅度减少。结论CR在小乳房钼靶摄影中优于传统的屏-片系统。
Objective To compare the advantages and disadvantages of CR system and screen-sheet system in small breast mammography. Methods A total of 233 small breast examiners underwent mammography using the Giotto high frequency mammography machine, the screen-plate system and the Japanese FUJIFILMXG5000 CR system. The applications of the two methods were analyzed. Results The quality of the images produced by the CR system was significantly better than that of the screen-sheet system, with a significant decrease in the rate of remake and a substantial reduction of radiation received by the subject. Conclusion CR is superior to the traditional screen-plate system in small breast mammography.
